TECHNICAL FIELD

The invention relates to encasements, and, more specifically, is relatedto adaptable mattress and/or box spring encasements.

BACKGROUND

Bed bugs are on the rise all over the world, having increasedapproximately 500 percent over the last three years in the Unites Statesalone. Pest control professionals report infestations in hotels,multi-family housing, apartments, and hospitals. Although mostlyeradicated in the U.S. around World War II, the current resurgence isattributed to an increase in international travel and immigrationcombined with less frequent use of strong pest-killing products.Mattress and box spring encasements protect bedding from bed bugs.

Additionally, over approximately 50 million people in the U.S. today areaffected by airborne allergens such as dust mites, mold, pollen and petdander. Those who are prone to allergies can suffer from itchy skin, hayfever, and other allergic symptoms because of the dust, pollen, and dustmites that are present in their beds. Allergy treatment professionalsrecommend allergen barrier encasements for bedding as a first line ofdefense for dust mite allergies and asthma. Encasing a mattress, boxspring, and/or pillow helps protect a user from inhaling allergens thatbecome airborne from the user's movement in bed. Encasements can be madeto be waterproof, breathable, fire-retardant, and impermeable to dustmites, bed bugs, mold, and bacteria.

FIG. 2 illustrates a perspective view illustrating an exemplaryembodiment of an encasement.

DETAILED DESCRIPTION

Disclosed are stretchable encasements or encasement systems for amattress and/or a box spring that are adaptable for use on at least twodifferent sizes (e.g., lengths, widths, and/or heights) of mattresses orbox springs. The encasements are of a size and/or type that prevents anddiscourages microbiological waste, organisms such as bed bugs, and/orother allergens from entering or egressing the encasement. FIG. 1illustrates a non-limiting exemplary embodiment of a mattress or boxspring encasement 100. The encasement comprises a cover 102 that has anopening 103 on at least one side of the cover 102, and in which theencasement substantially or completely covers a mattress or box spring(not separately depicted). The opening 103 may be secured closed with afastening means 104 and may be of any size or length, so long as it isconfigured to allow the mattress or box spring to be placed in theencasement 100.

It should be appreciated that the encasement can take the form of anyone of a number of shapes and sizes (e.g., lengths, widths, and/orheights) to fit a variety of types of mattresses or box springs. In oneembodiment, the encasement can fit at least two different sizes ofmattresses or box springs, with the proviso that the encasement is notthe exact dimensions of a standard U.S.-sized Twin, Long Twin, Full,Long Full, Hotel King, or California King mattresses or box springs. Inanother embodiment, the encasement can be the exact dimensions of astandard U.S.-sized Twin, Long Twin, Full, Long Full, Queen, King, HotelKing, or California King mattress or box spring, with the proviso thatit is configured to stretch in the height direction only. Additionally,the encasement cover may be manufactured from a number of differentmaterials, examples of which are discussed hereinbelow. These materialsmay be hypo-allergenic and/or porous. The encasement 100 can include afastening means 104, such as for example, but not limited to, a zipper,in which fastening means 104 may also be of a size and/or type thatprevents and discourages microbiological waste, organisms such as bedbugs, and/or other allergens from entering or egressing the encasement.It should further be appreciated that the depicted placement of thefastening means 104 on the cover 102 is merely exemplary, as it shouldbe appreciated that the fastening means 104 can be located on anysurface of the cover 102 such that the fastening means 104 is configuredto provide an opening 103 to open and/or remove the cover 102 from themattress or box spring.

FIG. 2 illustrates another non-limiting exemplary embodiment of anencasement 300. The encasement comprises a cover 302 that has an opening303 on at least one side of the cover 302, and which substantially orcompletely covers a mattress or box spring. The opening 303 may besecured closed with a fastening means 304 and may be of any size orlength, so long as it is configured to allow the mattress or box springto be placed in the encasement 300.

As noted above, the disclosed encasements can be made from a variety ofmaterials that are suitable for encasing mattresses or box springs, andof the type that discourages, decreases, and/or prevents microbiologicalwaste, organisms such as bed bugs, and/or other allergens from enteringor egressing the encasement. These materials may be hypo-allergenicand/or porous. In one embodiment, the encasement cover is a stretchablefabric dimensioned so that the encasement will stretch to accommodatevarious sizes (e.g., lengths, widths, and/or heights) of mattresses orbox springs in a fit that will discourage, decrease, and/or preventmicrobiological waste, organisms such as bed bugs, and/or otherallergens from entering or egressing the encasement. For example, theencasement cover may be dimensioned to accommodate the mattress or boxspring of beds of at least one of the following three sizes, such as forexample: (1) a Twin and Long Twin; (2) a Full and Long Full; or (3) aHotel King and a California King.

For example, the encasement cover can be made of a stretchable fabricmade of a synthetic elastic polyurethane-polyurea copolymer, also knownas spandex or elastane (brand names of which include Lycra® (made byInvista), Elaspan® (Invista), Creora® (Hyosung), ROICA® and Dorlastan®(Asahi Kasei), Linel® (Fillattice), and ESPA™ (Toyobo)). For example,the encasement cover can be made of a fabric comprising any fiberblended with spandex, which can become stretchable, elastic, and providea close fit around a mattress or box spring that is desired in anencasement. The fiber blended with spandex may be, for example, cotton,nylon, polyester, a microfiber, and/or combinations thereof.Alternatively, the fabric of the cover can be made of any of thefollowing exemplary materials, such as but not limited to, spandex,cotton, nylon, polyester, a microfiber, and/or combinations thereof solong as the encasement can stretch to fit at least two different sizesof mattresses or box springs and provides the close fit desired in anencasement. The polyester can be a polyester knit or polyester stretchfabric. The polyester knit fabric may be, for example but not limitedto, a “mock interlock knit” (also referred to as a no-run interlock). Inone embodiment, the polyester stretch fabric has the property of 105grams per square meter (GSM).

In one embodiment, the stretchable fabric of the cover may have anoptional laminate thereon on all or any part of the encasement thatfurther discourages, decreases, and/or prevents microbiological waste,organisms such as bed bugs, and/or other allergens from entering oregressing the encasement. The laminate may be, for example but notlimited to, a polyurethane membrane. The polyurethane membrane may be,for example but not limited to, a 1 mil polyurethane membrane or a 2 milpolyurethane membrane. In one embodiment, the polyurethane has over 200%stretch and recovery, and therefore conforms or stretches with thestretchable fabric, and aid the fabric in its recovery. In oneembodiment, the polyurethane is adhered to the stretchable fabric.

In one embodiment depicted in, for example, FIG. 2, the top coverportion 308 is made of a stretch knit polyester fabric with a layer ofpolyurethane membrane laminated thereon and the bottom cover portion 310is made of interlock stretch knit polyester with no layer ofpolyurethane membrane laminated thereon. In an alternative embodiment,both the top cover portion 308 and the bottom cover portion 310 are madeof a stretch knit polyester fabric, with the stretch knit polyesterfabric of both the top and bottom cover portions 308, 310 having a layerof polyurethane membrane laminated thereon. In the embodiment depictedin FIG. 2, an optional horizontally-oriented seam 312 mates the topcover portion 308 with the bottom cover portion 310. The seam 312 mayrun around all or a portion of the encasement 300. The encasement may bemanufactured from a number of different materials, examples of which arediscussed hereinbelow.

The fastening means 304 (e.g., a zipper) may also be of a size and/ortype that prevents microbiological waste, organisms such as bed bugs,and/or other allergens from entering or egressing the encasement. Itshould further be appreciated that the depicted placement of thefastening means 304 on the cover 302 is merely exemplary, as it shouldbe appreciated that the fastening means 304 can be located on anysurface of the cover 302 such that the fastening means 304 is configuredto provide an opening 303 to open and/or remove the cover 302 from themattress or box spring. In one embodiment, the fastening means 304 islocated at the approximate center of the height of the encasement,between the top cover portion 308 and the bottom cover portion 310. Thefastening means can be located closer to the top cover portion 308 orthe bottom cover portion 310 than the exact location depicted in FIG. 2.

It should be appreciated that the encasement can take the form of anyone of a number of shapes and sizes (e.g., lengths, widths, and/orheights) to fit a variety of types of mattresses or box springs. In oneembodiment, the dimensions are not the exact same dimensions of astandard U.S. bed size. For example, the dimensions of the encasementcan vary anywhere between the size of a standard Twin and a Long Twin,or between the size of a standard Full and a Long Full, or between thesize of a Hotel King and a California (or Western) King. The dimensionsof the encasement will vary as a function of the elasticity of thefabric of the encasement. In other words, a more highly elastic orstretchable fabric cover can be made of smaller dimensions than anencasement cover made of fabric that is less elastic or stretchable.
